What are the recycling methods for waste textiles? How to reuse them?

As a very common thing in the market now, waste textiles have already posed certain challenges to the reuse of resources, because of their continuous appearance, which is of course related to our current lifestyle, and conservation has long become a big problem. Fortunately, products such as openers are constantly appearing, providing strong support for us to solve this problem. Today, let's talk about several different ways to recycle and reuse waste textiles. Reuse after chemical degradation Chemical degradation recovery is a method that can achieve material recycling. It is to depolymerize the polymers in waste textiles at high temperature to obtain monomers or oligomers, and then use these monomers to re-manufacture new chemical fibers. For polymers synthesized by polycondensation, such as polyester fibers and nylon fibers, depolymerizers must be added during the degradation process. Olefin polymers, such as polyethylene, polypropylene, polystyrene, etc., need to be degraded in a reducing gas atmosphere. At present, this method has achieved large-scale production in the recycling and reuse of some high-value chemical polymer materials. In addition to the product structure and performance that cannot meet the actual use requirements of new functional waste textiles after chemical modification, the polymer structure and performance of the fiber raw materials have not changed fundamentally. Therefore, the recycling of waste textiles can be achieved through chemical modification. This method achieves functional changes in waste textiles through chemical methods such as grafting, cross-linking, and hydrolysis. For example, waste acrylic fibers that produce cyanide during combustion can be hydrolyzed to change from static-sensitive materials to water-absorbing materials. The hydrolyzed products of waste acrylic fibers have a wide range of applications and can be used as adhesives, printing and dyeing auxiliaries, soil conditioners and water-absorbing materials for agricultural production and urban vertical greening, mud treatment agents for oil fields, polymer scale inhibitors, etc. In recent years, they have also been used in the preparation of ionic fibers and new functional materials. A new look after physical reorganization Except for some fibers that are worn and broken, most of the fibers in waste textiles still maintain good performance. Therefore, non-woven forming technology can be used to recycle waste fibers. Through mechanical treatments such as shearing and tearing, knitted and woven fabrics can be transformed from fabrics into short fibers, and then formed into fiber nets by mechanical combing or air-laid web formation. After being reinforced by needle punching, hot rolling or hydroentanglement, they can become non-woven materials with functions such as sound absorption, sound insulation, heat insulation and warmth preservation, which can be used as fillers, automotive sound-absorbing materials and carpets, geotechnical materials, building materials such as insulation boards, roofing felts, and low-grade blankets. They can also be impregnated with resin to become boards, which can be used as home decoration materials and automotive door panels and body panels. We found that the working principle of recycling tools such as openers is still very advanced, which is indeed of great benefit to our resource protection.
